CURB-FINISHING TOOL.

Application filed April 24, 1923.

T 0 all whom it may concern Be it known that I, OLE FYHRIE, a citizen ofthe United States, and resident of Racine, in the county of Racine andState of lVisconsin, have invented certain new and useful Improvementsin Curb-Finishing Tools; and I do hereby declare that the following is afull, clear, and exact description thereof.

'li his invention relates to curb finishing too s.

In finishing curbs it has been the usual practice to pour the horizontalportion and allow it to harden, and, thereafter, to pour the verticalportion. After these two portions have set, a finishing coat of cementis applied, and the usual practice has been to use a form, which is heldin position by an operator kneeling beside the curb, and is pushed alongto shape the finishing coat of cement to the exact gradually curvedcontour which is so much desired in this type of work. v

This process has been extremely slow and the tools have been soconstructed that a right and a left hand tool was needed or else onlyone direction of operation was permitted. In addition to this itnecessitated the operators holding it in place with both hands while heknelt beside the curb, necessarily resulting in extremely slowfinishing.

This invention is designed to overcome the above noted defects, andobjects of this invention are to provide a curb finishing tool which isadapted to be operated in either direction and which may be pushed alongby one or more operators while they walk along the portion of the streetadjacent the curb, thus providing a tool which may be operated atmaximum speed and with the least possible effort to produce a perfectlyfinished curb.

Further objects of this invention are to provide a curb finishing toolin which elongated handles are provided and are adjustably secured tothe tool so that one of the handles may be employed to advance the toolwhile the other may be employed, and if desired by a separate operator,to hold the tool in position by furnishing the necessary lateralpressure.

An embodiment of the invention is shown in the accompanying drawing, inwhich:

Figure 1 is a sectional view through the curb showing the tool inposition and partly in section.

Serial No. 634,230.

Figure 2 is a plan view of the structure shown in Figure 1.

In forming a curb a pair of side boards 1 and 2 are temporarilypositioned and the horizontal and vertical portions 3 and fl:respectlvely are successively poured and allowed to harden; thereafter,finishing cement is positioned over the roughly formed curb and afinishing tool is slid thereover.

The tool comprises a heavy sheet metal plate 5 having any desiredcontour, such as shown in Figure l, and comprises a horizontal portion,an upwardly extending portlon, and a shorter horizontal top portion. Themarginal edges of this tool are upturned as indicated at 6 so that thetool may freely be pushed in either direction, the curved marginal edgeseasily riding over and forcing down the finishing cement. It will benoted that the upturned edge at each margin braces the structurematerially, but to furnish a further bracing action,.a pair of bracemembers 7 are provided and are riveted to spaced portions of the deviceas may be seen from Figure 2.

A series of rollers 8 are carried by suitable supports riveted to theupper side of the apparatus and are adapted to project through apertures9 formed in the body portion 5. These rollers are so positioned thatthey travel upon the upper edges of the boards 1 and 2 as may be seenfrom Figure 1.

A substantially centrally located casting 10 conforming to the curvedcontour of the body portion, as may be seen from Figure 1, is riveted orotherwise secured in posit-ion and, as shown, approximately centrally ofthe body portion. This casting carries an upwardly projecting pin 11upon which are pivoted the hubs 12 and 13 of elongated handles 14 and15. These handles may conveniently be formed of wood and riveted toextensions projecting from the hubs, as shown.

In using the apparatus, one operator grasps the handle 15 and walkingalong the side of the curb pushes the tool at a substantially uniformand relatively rapid rate along the curb, the other operator presses thehandle 14 inwardly, thereby holding the tool in position and maintainingthe requisite pressure. It is to be noted that both handles pressdownwardly and thereby secure the necessary downward pressure for thetool.

It is to be particularly noted that the tool is so constructed that anoperator may wall: along the street adjacent the curb and may rapidlyfinish the curb. There is no danger of the tool movingout of position asit is held inwardly by the handle 14:.

It will thus be seen that a curb. finishing tool has been provided whichmay be 0p erated in an extremely simple manner and whibch will produce awell finished smooth cur It will further be seen that a large amount offriction is avoided by providing the rollers 8 and that, therefore, aminimum of effort is required to operate the tool.

It will further be seen that the tool may be operated in eitherdirection and is, therefore, very effective in ordinary street work.

I claim:

1. A curb finishing toolcomprising a blade having horizontal andvertical faces and upturned transverse marginal edges, and a pair ofelongated handles pivotally secured to the blade substantially centrallythereof, whereby the blademay be pushed longitudinally in eitherdirection and forced transversely and downwardly simultaneously with thepushing operation.

2. A' curb finishing tool comprising a blade having horizontal andvertical facesand upturned transverse marginal edges, and a pair ofelongated handles pivotally secured to the blade substantially centrallythereof, said handles being inclined upwardly and outwardly to permitfree manipulationby two operators, whereby the blade maybe pushedlongitudinally in either direction and forced transversely anddownwardly sin1ultaneously with the pushing operation.

3. A curb finishing tool comprising a blade having horizontal andvertical faces and upturned transverse marginal edges, a stud carried bythe blade substantially centrally thereof, and a pair of elongatedhandles pivotally mountedon said stud whereby the blade may be pushedlongitudinally in either direction and forced transversely and down-vwardly simultaneously with the pushing op: eration.

4. A curb finishing tool comprising ablade having horizontal andvertical; faces and;

upturned transverse marginal edges, and, a pair of elongated handlespivotally secured to the blade substantially centrally thereof, both ofsaid handles being inclined u,pwardly, whereby downward pressure may beexerted upon the blade, one of said handles being adapted to extendlongitudinally of the blade in either direction for pushing the same,and the other of said handles be ing adapted for positioning at various;angles to the first mentioned handle, where by the longitudinal andtransverse oomponentsof the force transmitted through; said. lastmentioned handle maybe varied,

In testimony that I claim the fQr going I have hereunto set my hand atRacine i nl the.-
